Those eggs that had l)een some three or four weeks in the "incnhator" 

 usually had thicker and more permanent veils than those that opened 

 two or three days after collecting, while those found in the open fields had 

 veils well developed if eggs opened during rainy weather. Also those 

 plants that opened after cold weather c^me had veils. Specimens of 

 Phallus rulicurdiis collected at Aust'p, Texas, during April. May and 

 June, have no sign of a veil of any kind, not even the alcoholic material 

 (of which T have some ten to fif*'een specimens), shows any trace of a veil.' 

 Considering these facts, it would seem that this layer of tissue that some- 

 times tears lose and forms a veil and sometimes does not, acts as an 

 organ of nutrition in which is stored, or through which passes, food to 

 he used hv the stipe and cap; if this he the case, then in warm, damp 

 weather the maturing stipe and cap would use most of this in their de- 

 velopment, so that at elongation of plant no real veil would appear. In 

 ot^er words, it would clino- to the under side of the cap and to tl^e inner 

 surface of the volva ; hut if the amount of water during the growing sea- 

 son was in excess of the quantity u.suallv present, then this tissue with 

 others would be more strongly developed than normallv and. therefore, 

 would be more likely to appear as a veil at maturity of the plant; or if 

 from any cause, as cold, removal from earth, etc.. the later develonment 

 of plant should be checked, then tins tissue would appear as a veil; this 

 is only an hynothesis, the proof of which remains yet to he worked out. 

 At any rate the fact remains that in these two species the veil may or 

 may not be present, and when present may be a mere thin membrane or 

 ore of appreciable thickness and permanency Hipt will and does persist 

 when the plants are dried or when kept in fluids. The presence of a 

 ■v-eil on Phalhis iivhvd'rus has been noted and discussed before by Van 

 I'ambeke. also by Ed. Fischer. 



Phallus impvdicus, I., ^'ar. imhcrialis, Schiv. This was our most 

 al)nndant Phallus in the Fall of 1902. It was first collected Oc<^o1)er the 

 twentiet'i and snecimens were found from then till the middle of January. 

 1903. On October the twentieth the two large bunches of e"-gs were 

 fo'md in a If^w, d'mn nlace, rich in vegetable deliris. one bunch was s'l 

 badly eaten by the fly larvae that none of the ep^gs hatched, b'lt two of 

 ti-e eggs of the larger hunch hatched. This bunch is seen in photo^ra|)h 

 No. 1. then No. 2 shows it with two eggs hatched, and some had 1ieen re- 

 mo'' ed from bunch l^eing destroyed by the larvae.
